Shot in the dark but could be 2 problems. Leaky valve cover gasket- my spark plug holes used to fill up with oil before I replaced the gasket. Plus loose or cross threaded spark plug. The oil would be constantly leaking into the engine and would burn off and produce smoke. The leak is small enough that there is no noticeable smoke while it is constantly burning the drip off. When you park it for awhile the drip adds up to enough oil in the engine to see smoke. With plugs in place, stick a paper towel down in the spark plug holes and see if it comes out dripping with oil. If it does, see if they are all tight. if they are, check your threads for damage or any other way the oil could leak into engine. I am not a mechanic but I did have a lot of smoke at startup after I pulled a plug, forgetting that the hole was filled with oil from a leaky gasket.

Valve guide seals and possible the actual valve guides are worn out but a new set of seals will help but to change these you will have to remove the cylinder head

1991 mazda mx5 eunos roadster radiator clogged with oil

Your radiator is leaking internally, leaking transmission fluid from the transmission fluid cooler into the radiator where the coolant is. You can't fix it, just get the radiator replaced and then flush the coolant.

1993 Mazda B2200 smokes blue smoke for 2 min.on start up only after setting overnite. does not smoke otherwise.Replacing valve guide seals did not help. compression test is good.What is the problem?

The oil rings on the pistons may be stuck, gummed up. I would remove the spark plugs and and see if you can find some Combustion Chamber Cleaner or some other type of cleaner that will cut carbon and oil sludge. Put about .5 oz in each cylinder over night and in the morning spin the enigne over a few timers and then replace the plugs and go drive it a few miles. That may get the rings unstuck.

Honda Accord 1994 V4 LX: Starting problems in the morning

There could be a few things causing this. When the car finally starts, is there any smoke coming out the exhaust pipe? White smoke would mean your headgasket is leaking and is letting coolant into the engine, then it is burned along with the fuel. Does the car run hot? Meaning has it ever overheated? Back to the smoke, if its black, your oil is getting in and is burning.

Now, the reason why it would be hard for a car to start, could be, a leaking headgasket, flooding the car while the car is sitting.

And yes, the car would be able to crank, but just wont start, for a while...because it has to get rid of all that fluid that has leaked into the engine while sitting at night.

Another thing you could look at, is your fuel pump, is it supplying a sufficient amount of pressure? If it isnt, it will take a while for it to pressurize and deliver fuel into the engine. You can check the fuel pump yourself by renting a fuel pump pressure tool from stores like autozone, kragen and more.

Your gas cap on tightly?

Good luck with your problem.

Idle problems

With the engine running at normal temperature, put a bent paperclip between gnd and ten in the diagnosis box (
Left side of engine bay above the shock tower)
Under a plastic bung on the throttle body where the big black tube fits in near throttle cable, turn the screw until the revs are about 800-900 rpm ,Remove the clip and your done!.
